I'm hoping someone might be able to shed some light on a Validation error
Ive just started getting in the Custom UI Editor while updating some
screentips and supertips in an Excel XML file (actually an *.xlam file). The
error is:

€œThe 'screentip' attribute is not declared.€�

As I had successfully used both the attributes in this file previously, I
dont understand why I am now getting this error. Can anyone shed any light
on this?

Thanks for any insights!
